The invention relates to the technical field of energy absorption structures, in particular to a bird nest imitating multi-level energy absorption structure. A multi-level energy absorption structure imitating a bird nest comprises a polygonal pipe, a plurality of level energy absorption pipes are arranged in the polygonal pipe and are arranged inwards in a staggered mode layer by layer, the energy absorption pipe located on the outer layer is connected with the polygonal pipe, and the adjacent level energy absorption pipes are fixedly connected. Each energy absorption pipe is composed of a plurality of edges, and the edges forming the energy absorption pipes are arranged in a crossed mode according to set angles. The energy absorption pipe is composed of a plurality of edges, the multiple layers of energy absorption pipes are arranged in a staggered mode inwards layer by layer, and when observed from top to bottom, the energy absorption pipe is of a bird nest imitating structure. In the collision process, the hierarchical structures interact, stack and deform, more wrinkles are generated, the wavelength of the wrinkles is shorter and more uniform, the energy absorption is greatly improved, and the initial peak force is reduced.

    本发明涉及吸能结构技术领域,尤其是涉及一种仿鸟巢的多层级吸能结构。一种仿鸟巢的多层级吸能结构,其包括多边形管、所述多边形管内部设置有多个层级吸能管,多个层级吸能管逐层向内交错布置,位于外层的吸能管与多边形管连接,相邻层级吸能管之间固定连接;吸能管均由多个边组成,组成吸能管的各个边按设定角度交叉设置。吸能管由多个边组成,多个层级吸能管逐层向内交错布置,从上往下观察,呈现仿鸟巢结构。在碰撞过程中,各层级结构之间相互作用堆叠变形,产生褶皱数量更多,褶皱波长更短,更均匀,能量吸收大幅提高且初始峰值力降低。
